Color Light Studio's Igor Penjivrag first entry into the WordPress plugin world is called Author Exposed.
When one of your blog readers clicks on a post author's name, rather than sending them the to the author's site or showing their WordPress profile information, Author Exposed pops a mini window that includes the author's name, email address, linked site address, a short profile, a link to an archive of their posts and their gravatar.
The screen capture above shows Igor's author profile from his site.
The only change that I made to the plugin was to remove the code that showed the author's email address from showing up. (There's enough spam in the world already).
Great work, Igor! Thanks for the plugin!
